Magnum reseal questions?..

So I'm going to pull the Magnum out of my 98 2500.. I just ordered the Hughes intake manifold repair kit.. I'm dropping a quart of oil seemingly every hundred miles. Nothing on the ground and it doesn't seem to smoke whatsoever. No check engine lights.. my plan is to just pull the motor completely. I'd like to put it on my engine stand and reseal... I was very much hoping to flop the AC compressor off to the side so I don't have to get into de-charging and recharging? I would like to repaint the engine Maybe like corporate blue or something so I can detect oil leaks in the future? Plus I like the color.. I would like to give the engine they say a good scrubbing while the engine is out. Well I have it out I'm thinking of the timing chain? Are they like the old LA Motors? It only has a hundred and thirty thousand miles.. I'd like to change the rear main seal and anything else..
I'm looking for any dues or don'ts? I appreciate everybody's experience and help ahead of time... Thank you..
268,*** miles on mine. Many out there with 300+k miles. You wouldn't need to do all that. Just the intake job. However, means you'll have the motor out...…
